WebGabapentin is a prescription medication known as a gamma aminobutyric acid (GABA) analogue. GABA reduces the excitability of nerve cells (neurons) in the brain, which play a role in seizures and the transmission of pain signals. Gabapentin mirrors the effects of GABA calming excited neurons. WebThe mechanism by which gabapentin exerts its anticonvulsant action is unknown, but in animal test systems designed to detect anticonvulsant activity, gabapentin prevents seizures as do other marketed anticonvulsants.
